If you want to change your username let me know and it can be done, as long as it hasn't already been taken. It will be also mean that you login name changes too so think carefully about it. In the old message boards name display is all that changed. This changes the login and display. If you change it all of your posts will still be under the new name too PM any requests to me.
Everyone has their default login name right now because the server doesn't allow a display name.
